The busy bees over at BMW's Munich headquarters are nearing the completion of the development phase of the newest addition to their crossover range, the sportier looking X4 that we first laid eyes on as a concept model at the Shanghai Auto Show earlier this year.
In this spy video that comes to us via the crew from Bimmerpost , a number of X4 prototypes were filmed testing both on public roads and of course, the Nürburgring, which has become a second home to all German (and not only) carmakers.
Like the X3 with which it shares everything under the skin and its bigger brother, the X6 as well as the X5, the new X4 will be manufactured at BMW's Spartanburg factory in the USA, with production and consequently sales, scheduled to start in 2014.
While we know that the regular diesel and gasoline powertrain options will be common with the X3, the question remains whether BMW will place an "M" moniker along with a more powerful turbocharged engine in the X4.
